But, like last year, Austin area U.S. Post Offices will not stay open until midnight. Post offices across the country are cutting down on late hours for tax day. That’s because most people now file online.

"According to the Internal Revenue Service, this year over 90 percent of tax returns nationwide have already been electronically filed online," USPS said in a press release. "Of the 148 million returns the IRS expects to be filed this year, only 23 million will be paper returns, down seven percent from last year."

USPS spokesperson Sam Bolen strongly encourages postal customers mailing tax returns to use correct postage (the IRS will not accept mail with postage due) and to carefully check the last pick up time posted on the collection box when mailing.
